Command Pulse Output Form - Mitsubishi Electric MELSERVO MR-MT2010 Instruction Manual

6. MR-MT2200 PULSE I/O MODULE

6.7.4 Command pulse output form

The following three different types of output pulse commands are available.
Connection form
Differential line driver
connection
Open-collector connection
Differential line driver
connection
Open-collector connection
Normally, the driver of the stepping motor, etc. has restrictions on the timing (interval time) of command
pulse for switching the motor rotation direction. Considering the restrictions of the driver, set the dwell time
(time when pulse is not outputted) to the controller for switching the motor rotation direction.
An output change equivalent to when the command pulses are outputted may occur at the following timing of
the pulse I/O module. (e.g. at initial setting of polarity and setting of output polarity)
When the pulse I/O module is on
When the pulse I/O module is off
At the first connection to SSCNET III/H communications
At the reconnection to SSCNET III/H communications
(1) In station mode
Select the output functions with [Pr. PTC004] for A-axis and [Pr. PTC020] for B-axis.
(2) In axis mode
Select the output functions with [Pr. PB14].
